Fleshed out TMStagedTweet state machine calls and added a tweet_struct JSONField.
CharSignatureField compiles OK.
Added initial stuff for TMStagedTweet model, with fancy metaclass crapola in the StateModel implementation that is about to get axed.
Renamed chapter header inclusion tag template (that's 'chapter', with a 't' in it) and polished off the skeleton code for the tag function itself.
